The Question Will Be Wrong It Must Be,

A body covers one-half of its journey at 40 m s^-1 and the next half at 50 m s^-1. Its average velocity is?

Explanation:

Solution:

Average velocity=Initial velocity+Final velocity By 2

So,

40m/s-1 + 50 m/s - 1 By 2 = 90m/s - 1 By 2

So,

The answer is = 45m/ s-1
